TBS 3D fingerprint reader qualifies as finalist in IARPA N2N Challenge
The challenge posed the question: “Can you build the best autonomous nail to nail fingerprint capture device?”
TBS says traditional touch fingerprint technologies have limited resilience to environmental conditions, image and template quality affected by contact with the surface, difficulties with shallow fingerprints, and difficulties recognizing liveness. The company submitted a slightly modified version of its 3D Touchless Terminal, which captures images from multiple angles.
An 8-year old sensor was used, the company says, due to the strong privacy mechanisms of its newer and more advanced devices. Despite this, it was one of the two (out of nine) solutions which scored 100 percent at fingerprint acquisition of over 3,000 samples.
The 3D Terminal uses 3 different cameras surrounding the finger and a complex illumination system to capture a wide area in high resolution in less than two seconds, and features integrated self-learning functionality and liveness detection, according to TBS.
The winners of the challenge will be announced on March 21 as part of the Biometrics Institute’s U.S. Conference.
